Coronary artery bypass surgery in a patient with Kartagener syndrome: a case report and literature review
Journal of Cardiothoracic Surgery volume 5, Article number: 68 (2010)
Kartagener syndrome consists of congenital bronchiectasis, sinusitis, and total situs inversus in half of the patients. A patient diagnosed with Kartagener syndrome was reffered to our department due to 3-vessel coronary disease. An off-pump coronary artery bypass operation was performed using both internal thoracic arteries and a saphenous vein graft. We performed a literature review for cases with Kartagener syndrome, coronary surgery and dextrocardia. Although a few cases of dextrocardia were found in the literature, no case of Kartagener syndrome was mentioned.
In 1606 Hieronymous Fabricious described situs inversus, while in 1643 Marco Severino described dextrocardia . Situs inversus is a rare congenital disorder with an incidence of 1:10000, in which the major visceral organs are reversed from left to right in a mirror image of the normal condition . Kartagener syndrome consists of congenital bronchiectasis, dextrocardia and sinusitis .
A patient with Kartagener's syndrome and three-vessel coronary disease was referred to our department for bypass surgery. We searched the literature about the Kartagener's syndrome in order to find references about the choice of conduits and the position of the surgeon in patients with mirror-image appearance of the heart. Several cases of surgical coronary revascularization in patients with dextrocardia have been reported in the literature, but no case was referred as Kartagener's syndrome. We report a case of a patient with Kartagener's syndrome with total situs inversus, bronchiectasis, chronic respiratory disease and three-vessel coronary disease, being treated in our institute with coronary surgery using both internal thoracic arteries. To the best of our knowledge this is the first report of coronary surgery in a patient with Kartagener syndrome.
Case Report and Review
A 56 year-old Caucasian male patient was admitted to our department for scheduled coronary artery bypass due to three-vessel coronary disease. The patient was already diagnosed as Kartagener syndrome with total situs inversus and azoospermia (patient had no children). A CT scan of the thorax showed bronchiectasis of the lungs and dextrocardia (fig. 1). The coronary angiography was performed without particular difficulties and revealed a proximal stenosis of 90% in the left anterior descending artery (LAD), a proximal stenosis of 90% in the circumflex artery and a stenosis of 99% between the proximal and middle part of the right coronary artery. The ejection fraction was normal and the aortic valve was competent. A spirometry was performed which revealed a reduction of the Forced Expiratory Volume, with a FEV1 of 1.44 L (40.6% of predicted value) and a reduction of the Forced Vital Capacity, with a FVC of 1.80 L (38.7% of the predicted value). Due to the patient's severe pulmonary disease an off-pump operation was decided.
The chest was entered through a median sternotomy, with the surgeon standing on the left side of the patient. The heart had an exact mirror image of a normally positioned heart and showed a good contractility. Both internal mammary arteries (IMAs) and a saphenous vein graft (SVG) were harvested. The LAD was opened and grafted with the left internal mammary artery (LIMA). Then the first obtuse marginal branch of the circumflex artery was grafted with right internal mammary artery (RIMA). Finally, the posterior descending artery (PDA) was grafted with the saphenous vein graft. The proximal anastomosis of the vein graft was then performed on the ascending aorta. After haemostasis, the chest was closed in routine fashion. The patient was extubated six hours later and remained in the Intensive Care Unit for three days due to his respiratory disease and increased volume of secretions. He was discharged from the hospital on the 10th postoperative day.
Kartagener's syndrome is characterized by the triad of bronchiectasis, sinusitis and situs inversus, and is also combined with abnormalities of the cilia of the respiratory epithelium. Some male patients with Katagener's syndrome also have sterility due to dyskinesia of the spermatozoa .
Total situs inversus is a rare condition which does not preclude long-term survival. Patients with dextrocardia and coronary disease may present for coronary bypass surgery. The mirror-image site of the heart and the great vessels does not impose a problem for carrying out a normal coronary artery bypass grafting operation, as it can be seen in the literature.
Saad et al reviewed the literature for coronary surgery in patients with dextrocardia, dealing with the position of the surgeon . We reviewed the literature in order to ascertain the conduit choice of each surgeon, especially concerning grafting of the left anterior descending artery (Table 1).
Most of the authors preferred to graft the LAD with the right internal mammary artery, as the mirror-image appearance of the heart offers the convenience of using this arterial graft.
Seedio et al. reported a series of two patients . In one case they used LIMA as a free graft to graft the LAD. Tabry et al. anastomosed the free LIMA to the RIMA and then they grafted the LIMA to the first diagonal branch and the LAD . Kuwata et al. harvested both internal mammary arteries and both radial arteries, skeletonized the LIMA and managed to use it in-situ to graft the LAD . Chakravarthy et al. reported two cases . In the first case, they used LIMA in-situ to graft the LAD, whereas in the second case they used the RIMA. Yamashiro et al. used both IMAs and the radial artery, which was anastomosed to the LIMA and then to the second obtuse marginal branch (OM2) and PDA in a sequential manner . RIMA was anastomosed to the LAD and LIMA grafted the OM1 branch. In older reports (Grey and Cooley, Irvin, Yamaguchi, Astudillo, Nomoto) saphenous vein grafts were exclusively used [9–13].
In our case the use of the left internal mammary artery to graft the left anterior descending artery was feasible, as the stenosis of the vessel was proximal and the length of the arterial conduit imposed no technical difficulty. We preferred the use of the LIMA to the LAD as the literature has strongly proven the excellent results of this anastomosis . RIMA was skeletonized and used to graft the obtuse marginal branch of the circumflex artery. Finally, performing the operation "off-pump" did not constitute a problem in our case, as the patient was haemodynamically stable throughout the procedure allowing us to have access to all coronary vessels, without the need of conversion to "on-pump" operation, as occurred in the case of Bonde and Campalani . The use of cardiopulmonary bypass was omitted in our patient because of his poor respiratory function.
Situs inversus with mirror-image of the heart is a rare condition, which eventually every cardiac surgeon might have to deal with. The position of the surgeon depends mainly on the surgeon's choice. The use of the RIMA seems to be the easier way to graft the LAD, but when the lesion of the LAD is proximal LIMA can also be used to graft the LAD. In patients with Kartagener's syndrome and severe respiratory disease, off-pump bypass grafting could be performed.
